JOSEPH BOND, OF BUFFALO, NEW YORK.

RADIATOR.

SPECIFICATION forming part of Letters Patent No. 376,766, dated January24, 1888.

Application filed March 2, i887.

Be it known that I, J OSEPH Bonn, a citizen of the United States,residing in Buffalo, in the county of Erie and State of New York, haveinvented certain new and useful Improvements in Radiators, of which thefollowing is a specification.

This invention relates to certain improvements in'the construction ofscrew-threaded nipples and the mode of connecting direct rawill be moreclearly hereinafter described and clai1ned,reference being had to theaccompanying drawings, in which-" Figurel is a side elevation of one ofthe sections. Fig. 2 represents a side elevation of a series of thesections put together. Fig.

3 is a'vertical longitudinal central section through a full-sizednipple.

Fig. 4 is a side elevation of one of the nipples having a small portionbroken away to show a section through the flanged rim, showing a slightmodification. Figs.5 and 6 are vertical longitudinal sections, showingmodified forms of the rim on the turning flanges; and Fig. 7 is an endview of one of the nipples.

From the outside of the screw-threaded portions 1 and 2, forming thenipple, is extended a flange, 3. This flange 3 may or may not beprovided with a rim, 4, which rim may be of any suitable form, orsimilar to those shown in Figs. 4-, 5, 6, and 7, the object being toform a flange or rim on each side of the flange '3 to lap over or coverthe seams where the faces of the bosses 5 and 6 and the faces or sidesof the flange 3 meet when the sections are put together. The sideflanges, 4, also cover anyopenings or imperfections that may be betweenthe faces of the bosses and flanges,

and thereby improve the appearance of the joint and render it moreeasily made, more secure, and the radiator-sections less liable to getloose or out of place by careless handling.

The sections are made in any of the usual ways, and consist of thehollow portions 7 and 8,and are provided with the screw-threadedopenings 9 and 10 at the top and bottom. These sections are preferablymade of eastiron, and the nipples may be made of either malleable,wrought, or cast iron, but any other suitable material may be used.Stacks of radiatorseetions connected in this way may be disconnected atany point and one or more sections added or taken away from the stackwhile the.

radiator is set up for use without disturbing or disconnecting thesupply-pipe connected to the stack or series of sections. They areeasily put together or taken apart by a tool adapted for thatpurpose-for instance, the ordinary pipe-tongs with the jaws madesufficiently narrow to act only on the rim or periphery of the flange 3.

I claim as my invention 1. A right and left hand screw threaded nipplehaving a narrow circular flange extending outward from between the rightand left hand screw-threaded portions, in combination with the circularbosses 6 of the radiator-see tion, having their peripheries of the samediameter, or substantially so, as the periphery of the flange, and thefaces of which come flush together,and thereby form a continuous pipe atthe upper and lower portions of the radiator, substantially asdescribed.

2. A right andleft hand screw threaded nipple having a circular flange,3, extending outward from between the right and left handedscrew-threaded portions 1 and 2, and

provided wit-h a rim, 4, extending from each side of the periphery ofthe flange 3, for the purposes described.
